THEORY'S Ptolemy's main theory about the universe was...
• His theory was called the Ptolemaic Theory and was believed for about 1,500 years.
• The first person to make accusations to his theories was Tycho Brahe, another famous astronomer LIFE AND ASTRONOMYWORK Very little is known about Ptolemy's personal life, but we do know... • Born in Greece and descended from a Greek family
• Claudius was not only an astronomer, but
also a mathematician and a geographer
•He lived approximately 87-150 A.D. which is about 63 years
• His first observation was exactly on the 26th of March 127 A.D. and his last was on Feb. 2nd 141 A.D.
• Written on subjects such as, conjunctions, eclipses, occultations, and transits• Was suspected to be taught by Theon Of Smyrna
• Made observations about the length of a day
• He created a treatise in 13 books called, Almagest and it explains Ptolemy's theories on such topics as the sun, moon, eclipses, fixed stars, and his star catalogue Some pages of the Almagest → WHAT HE DID AS A MATHEMATICIAN • Wrote and created the book, Almagest (also known as a mathematical syntaxis and when translated from Greek to English means The Mathematical Compilation) which also included a a thirteen book explanation of astronomy that included a star catalog with 48 constellations.
• Also, has written the Analemma which tells you how to construct a sundial and Planisphaerium which told about stereographic projection.
WHAT HE DID AS A GEOGRAPHER
• He was the first person to use latitude and longitude to identify places.
• In his theory's he had Asia extending to far East which may have been a factor in Columbus's sail to the West.
• Wrote Optics explaining color, reflection, refraction, and mirrors of various shapes.
FAMOUS QUOTE BY CLAUDIUS PTOLEMY
" I know that I am mortal by nature, and ephemeral; but when I trace at my pleasure the windings to and fro of the heavenly bodies I no longer touch the earth with my feet: I stand in the presence of Zeus himself and take my fill of ambrosia."
